SPRING-BED.

- SPECIFICATION forming part of Letters Patent No. 534,610, dated February 19, 1895. Application filed November 24,1 894. Serial No. 529,862. (No model.)

To all whom it may concern.-

Be it known that I, GUYMAFERA, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Spring-Beds, of which the following is a specification.

This invention has for its object to provide a strong, simple, and durable spring-bed adapted to be readily applied to and removed from a bedstead either of wood or iron, and it consists in the several improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side view of a spring-bed embodying my improvements. Fig. 2 represents a top view of the same. Fig. 2 represents in full lines a view of one of the wires forming the bed bottom, and in dotted lines the adjacentwire interlocked therewith. Fig. 3 represents an end view of the construction shown in Fig.1. Fig. 4 represents a section on line 44 of Fig. 1. Fig. 5 represents a section on line 5-5 of Fig. 1. Fig. 6 represents a perspective view of one of the spring-supporting cross-bars. Fig. 7 represents a perspective view of one of the supplemental springs.

The same letters and numerals of reference indicate the same parts in all the figures.

In the drawings-a a represent metal sidebars which are made of angle iron, each being L-shaped in cross-section and therefore having two flanges S 9 one of which is vertical and bears on the inner side of the siderail 5 of a bedstead, while the other is horizontal and bears on the top of said side-rail. This construction enables the spring-bed to be firmly secured in place by the act of placing it upon the side-rails ot' the bedstead, as will be readily seen. The end portions of the side-bars are bent upwardly, so that the ends of said sidebars are raised, as shown in Figs. 1 and 3. To the raised ends are secured suitable cross-bars adapted to be engaged with the wire bed-bottom c hereinafter described.

I prefer to provide two. cross-bars d and d at each end of the bed, each crossbar having bent ears on its ends which are attached by bolts or rivets e to the raised end portions of the side-bars a, the said crossbars d (1' being separated by narrow crevices of sufficient v bed-bottom 0.

width to receive the end loops of the wire bed-bottom c, said loops being secured to the cross-bars by pins or rivets f passing through the cross-bars d d. Ordinary wire nails may be used as the pinsf, and said nails may be headed or otherwise secured at their lower ends to the lower cross-bar d or not.

9 g represent spring-supporting cross-bars, which are attached at their ends to the horizontal portions of the side-bars a and extend across the space between said bars, for the purpose of supporting supplemental helical springs it upon the upper ends of which the bed-bottom crests. The cross-bars g are preferably T-shaped in cross-section, each having-a horizontal web 12 and a vertical web 13. The vertical web of each cross-bar g has formed on its ends a tenon 14 adapted to enter an orifice formed for its reception in the side-bar a. The horizontal web 12 and the tenon 14 project sufficiently beyond the end of the main portion of the vertical web 13 to enable the horizontal web to bear upon the flange 9 of the side-bar a, while the tenon projects through the vertical flange 8 of said side-bar sufficiently to be offset or headed against the outer side of said vertical flange, as shown in Fig. 5. The cross-bars g are thus securely interlocked with the side-bars, as will be readily seen.

Each cross-bar g supports a series of supplemental helical springs h the upper ends of which bear against the under side of the wire Each spring 77. is formed at its lower end with hooks h 72. as shown in Fig. 7, said hooks being adapted to engage the edges of the horizontal webs 12 of the cross-bar g, so that the springs h may be engaged with said cross'bars either by bending one of the said hooks to place after the spring has been placed upon the crossbar, or by sliding the hooks upon the end of the cross-bar before it is affixed to the side-bars.

The wire bed-bottom c is composed of a series of wires 0 (Fig. 2 each bent so that it has a zigzag form, or in other words comprises a series of loops, and each extending across the width of the bed-bottom. The ends of the wires 0' are slightly bent backwardly to form hooks c and the loops and hooks of each wire are interlocked with the loops and hooks of the next wire, throughout the entire length of the bed, as shown in Fig. 2, the loops of each wire excepting those at the ends of the bed being interlocked with the loops of the two adjacent wires, while the end hooks are interlocked in pairs at the edges of the bedbottom, as shown in Fig. 2. The loops of the wires at the ends of the bed projectbetween the cross-bars d (1 above described, and receive the pins f, said pins passing through the loops and thus securely connecting the bed-bottom to the cross-bars d d.

c 0 represent helical wire guards which extend along the edges of the bed-bottom to cover the hooks c and prevent the latter from catching the bedding, &c. Said wire guards are formed to embrace the outer members of the loops of the bed-bottom, as clearly shown in Fig. 2.

It will be seen that the described construction constitutes a very strong, serviceable,-an d simple spring-bed, which can be readily applied to and removed from a bedstead.

It is obvious that the bed-bottom consti-- tuted as above described may be used with any suitably constructed supporting frame.

I claim 1. A spring-bed com prising metal sidebars bent upwardly at their ends, said side-bars being L-shaped in cross-section and adapted to bear on the upper and inner sides of the side-rails of a bedstead; metal cross-bars attached to said raised ends; and a wire bedbottom engaged at its end portions with said cross-bars.

2. A spring-bed comprising a supporting frame having raised ends, cross-bars attached to said ends, and a wire bed-bottom composed of a series of wires extending across the bedbottom, each having hooks at its ends and a series of interlocking loops, the loops of the end wires being engaged with the cross-bars, while the end hooks of the other wires'are interlocked in pairs along the edges of the bedbottom.

3. A spring-bed comprising a supporting frame having raised ends; cross-bars attached to said ends and each provided with a series of studs or pins; a wire bed-bottom composed of a series of wires extending across the bedbottom and each having hooks at its ends and a series of intermediate interlocking loops, the loops of the end wires being interlocked with the pins on the cross-bars, while the hooks at the ends of the wires are interlocked in pairs with each other at the edges of the bed-bottom; and helical wire guards extending along the edges of the bedbottom and inclosing said hooks.

4. Aspring-bed comprising metal side-bars which are L-shapedin cross-section and are adapted to bear on'the upper and inner sides of the side-rails of a bedstead, said bars having raised endsgtend cross-bars attached to the said raised ends and having means for engaging the ends of a wire bed-bottom; intermediate and spring-supporting cross-bars which are T-shaped in cross-section and have end shoulders bearing on the upper surfaces of the sidebars; and tenons below said shoulders engaged with the vertical flanges of the side-bars.

In testimony whereof I have signed my name to this specification, in the presenceot two subscribing witnesses, this 13th day of November, A. D. 1894.

GUY MAFERA.
